PROJECT PROCEDURES TIT 1.E: SYSTEM VERTICAL SLICE REVIEW REVISION: 4 DATE: 06/26/98 PAGE 3 OF 23 1.0 PURPOSE This procedure establishes the overall objectives, scope, and general approach for conducting the System Vertical Slice Review (SVSR) for Mdistone Unit 2. The purpose of the SVSR is to confirm that the selected system's physical and functional characteristic.s are in conformance with its licensing and design bases. The SVSR will provide independent verification, beycod Millstone Unit 2's quahty as.mrance and management oversight, that they have identified and satisfactorily resolved existing nonconformances with the design and licensing bases and documented and utihzed the licensing and design bases to resolve nonconformances
1.1 BACKGROUND
On August 14,1996, the Nuclear Regulatory Commission (NRC) issued a Confumatory order directmg the licensee to contract with a third party to implement an Independent Corrective Action Verification Plan (ICAVP) to verify the adequacy ofits efforts to establish adequate design bases i
and design controls. The ICAVP is to employ a review of selected Millstone Unit 2 systems to l provide indapandent verification that, for the selected systems, the Millstone Unit 2 Configuration Management Plan (CMP) has identified and resolved existing problems, documented and utihzed I i
licensing and design bases, and established programs, processes and procedures for effective l
configuration in the future.8 The corrective action verification program was ordered to include:
e an in-depth review of selected systems which will address control of the design and design basis since issuance of the operatmg license for each unit; e selection of systems for review based on risk / safety based criteria similar to those used in implementing the Maintenance Rule (10 CFR 50.65);
e development and documentation of an audit plan that will provide assurance that the quality of results of the Licensee's problem identification and corrective action programs on the selected systems is representative of and consistent with that of other systems; O

ICAVP team to both the NRC and the Licensee; and l e procedures for the ICAVP team to comment on licensee's proposed resolution of the 6ndmgs 1
I and remnendations.
l The ICAVP audit will be a multi-tiered approach using different and distmet mspection math ~h for each of a total of three tiers. This procedure covers Tier 1. In Tier 1, four systems will be inspected using a system vertical slice review process to test the thoroughness of the NNECo's l reviews in identifying potential nonconformances with the design and licensing bases.
1.2 APPROACH The ICAVP SVSR will review the configuration of the selected system through a combination of l
l inspectmg techniques including hmant reviews, calculation reviews, and plant walkdowns.
The SVSR will assess the CMP as it applies to the selected sptems through:
e a review ofplant records; e verification of current, as-modified plant conditions agamst design basis and licensing basis dommantation; e verification that design and licensing bases requirements are translated into operatmg procedures and maintenance and test prowdus, e verification of system performance through review of test records and/or obsenstion of testing of particular systems; and e review of proposed and implemented corrective actions for Licensee-identified design deficiencies.'

PROJECT PROCEDURES TITLE: SYSTEM VERTICAL SUCE REVIEW REVISION: 4 DATE: 06/26/98 PAGE 5 OF 23 Any discrepancies identified during the review, coupled with the type of discrepancy and its relative importance on the stmeture, system or components regulatory requirements, will provide the basis for SVSR reporting.
2.0 DEFINITIONS
. Design Basis ... that mformation that identifies the specific functions to be performed by a stmeture, system, or component of a facility and the specific values or ranges of values chosen for controlling parameters as reference bounds for design. These values may be (1) restramts derived from generally accepted statxf-the-art practices for achieving functional goals or (2) requirements derived from analysis (based on calculation and/or experiments) of the effects of a postulated accident for which a structure, system, or component must meet its functional goals.'
. Licensing Basis, for purposes of the SVSR, the licensing basis for Mdistone Unit 2 consists of that set ofinformation upon which the Commission, in issuing an initial operathig license, based its comprehensive detemunation that the design, construction, and proposed operation of the facility satis 6ed the Commission's requirements and prosided reasonable assurance of adequate protection to public health and safety and common defense and security.8 Current Licensing Basis (CLB) is the set of NRC requirements applicable to a specific plant and a licensee's written commitments for ensuring compliance with and operation within applicable NRC requirements and the plant-specific design basis (including all modifications and additions to such commitments over the life of the license) that are dmkM and in effect.
The CLB includes the NRC regulations contamed in 10 CFR Parts 2,19,20,21,26,30,40, 50, 51, 54, 55, 70, 72, 73,100 and appendices thereto; orders, license conditions; exemptions; and technical specifications. It also includes the plant specific design-basis information defined in 10 CFR 50.2 as documented in the most recent final safety analysis report (FSAR Amendment #48) as required by 10 CFR 50.71 and the licensing correspondence such as

. Engineering Design Bases (EDB) - The set of design constraints that are not included in the Licensing Basis but are implemented to achieve economies of operation, maintenance, procurement, installation, or construction. Such as:
. Infonnation that describes a system, stmeture, or component Operatmg values or parameters that are not reference bounds for design Information that identifies functions important for economic, maintenance, incta11ation, or other non-safety function of design basis systems, structures, or components Information and operating values describing the functions ofnon-safety systems e Calculations, descriptions, and other " outputs" Design Verification - The process ofindependently reviewing, confirnung, or substantiating the design by one or more methods to provide assurance that the design meets the specified design criteria and design inputs. The extent of design verification may range from a detailed check of the to'. I design to a check of the d: sign approach and the results obtamed.
